LASH FUNCTION
(
PINS
DP/FL
AND
DMO)
Pressing the flash function key [R] results in a calibrated
pulsewhichdrivestheelectroniclinecurrentinterruptervia
pin DP/FL. The DMO output is also activated during pulse
production (see Fig.23). After a flash pulse, an interflash
pause time t
ifp
of 800 ms is inserted to recover the power
supply for the dialler part.
The duration of the flash time depends on the resistor
options FTSA and FTSB (see Fig.25 and Table 7).
During t

, the reset delay time is inhibited.
